Yokomo D-171GA 1.3x9.5Turn (Green) Progressive spring for Drift 橫崛 Yokomo DP-GRA90W  [D-171GA]

A long type spring that provides a supple suspension that is essential for drifting. The total length is 32 mm, which was determined based on data obtained from actual driving on various circuits, and in addition to the 5 general types of equal pitch springs, there are also 4 unequal pitch types that allow for more detailed settings. Seed lineup.
Unequal length springs have parts with different pitches mixed together within a single spring, and while the fine winding parts compensate for small vibration absorption and mild initial response, the coarse parts firmly absorb the weight during large rolls. It is a product that has contradictory characteristics, contributing to improved traction. By combining with equal pitch springs, the setting range is greatly expanded and it is possible to obtain operation that suits each drifting style.
